向phpmailer添加文件类型验证 - Add a filetype validation to phpmailer?

Add a filetype validation to phpmailer?

我有一个phpmailer，它通过从文件输入字段循环遍历文件数组来附加文件。我怎样才能使它只允许PDF或DOC。如果尝试其他操作，脚本将停止并给出一个错误:"不支持文件类型。"只支持PDF或DOC格式。"

有什么建议吗?

foreach(array_keys($_FILES['files']['name']) as $key) {
        $source = $_FILES['files']['tmp_name'][$key];
        $filename = $_FILES['files']['name'][$key];
        $mail->AddAttachment($source, $filename);
}

您需要查看$_FILES['files']['type']并确保它与您想要的mime类型匹配。

foreach ($_FILES as $file) {
    if ($file['files']['type'] == 'application/msword' 
        || $file['files']['type'] == 'application/pdf'
    ) { 
        $source = $file['files']['tmp_name'][$key];
        $filename = $file['files']['name'][$key];
        $mail->AddAttachment($source, $filename);
    }
    else {
        die("You may only upload PDF and Microsoft Word documents through this form.");
    }
}
